SHOE-POLISHING MACHINE.

Specification of Letters Patent.

Patented Mar. 31,1914.

Original application filed November 11, 1912 Serial No780,626. Divided and this applicat'ibn filed January 25, 1913. Serial No. 744,099.

To all whom it may concern: Be it known that I, AUeUsT H. R. HELLER, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Shoe- Polishing Machines, of which the following is a specification.

The present invention relates to improvements in shoe polishing machines, and is designed especially to provide liquid-black ing feeding mechanism used in connection with brushing devices for polishing shoes.

The brushing mechanism is made the subject of a pending application, Serial No. 730,626 filed November 11, 1912, and the present application. is a division of said pending application.

The present application includes devices involving means for supplying liquid blacking to the shoes to be polished, and in this instance such means includes compressed air. And the invention consists in certain novel features and combinations and arrangements of parts whereby the blacking is supplied to the shoe, through the medium of the compressed air, at proper, predetermined times, as will be pointed out hereinafter.

In the accompanying drawings I have illustrated one complete example of the polishing machine, involving the blacking feeding means, constructed according to the best mode I have so far devised for the practical application of the principles.

In the accompanying drawings: Figure 1 is a plan view of part of the complete shoe polishing machine, the upper structure being omitted for convenience of illustration. Fig. 2 is a vertical central sectional view of a portion of the machine, and Fig. 3 1s a sectional view of an upper portion of the machine shown in Fig; 2, the parts being broken at line 1-l. Fig. 4 is a rear view of the machine, the casing being omitted. Fig. 5 is an enlarged detail view of one of the air pumps and actuating mechanism for the liquid-blacking feeding tank and devices. Fig. 6 is an end view of the tank in Fig. 5, the pump omitted, looking toward the left, and a portion of the tank broken away for convenlence of illustration. Figs 7 and 8 are enlar ed details of construction showing a pacfiing box and connection in the air pump pipe. Fig. 9 is atop plan view of} a portion of the blacking supply tank showlng an air pressure regulating valve for air contained in the supply tank. Fig. 10 is an enlarged detail view of means whereby a clutch is actuated intermittently, by the reciprocating carriage of the machine, for operating the air pump. Figs. 11 and 12 are respectively an edge view and a front view' of a ratchet wheel forming part of the clutch actuating device of Fig. 10. Fig. 13 is an enlarged detail, vertical, sectional view of the nozzle and its connections. Fig. 14 1s a front view of Fig. 13.

The entire machinery is inclosed within a suitable casing 1 into which the shoe 2 may be inserted for polishing. The shoe is supported upon an adjustable foot rest 3, and a reciprocating carriage 4 is adapted to move forward and backward in close proximity to the shoe to be polished. Upon the carriage are rotatably supported four brushes, as 5, 6, 7, and 8 arranged in pairs, and a fifth brush 9, the latter brush rotatmg in a horizontal plane and the former brushes rotating in a vertical plane, as will be understood.

The carriage is supported to slide on two operating shafts 10 and 11 and these shafts are operated from a motor 12 through the medium of the sprocket wheels 13 and 14, chains 15 and 16, and the motor driven wheels 17 and 18. The screw 19,'centrally located of the machine causes the reciprocation of the carriage 4:, and this screw is actuated from shafts 10 and 11 through the medium of sprocket chains 20 and 21 passing over suitable sprocket wheels. The reciprocation of the carriage is attained through the medium of the clutch mechanism 22 (Fig. l), and it is the reciprocating movement of this carriage that actuates the air pumps for the blacking-feeding mechanism. The hereinbefore described mechanism is more elaborately described and detailed in the above mentioned application, but I have thus described the mechanism in order to provide a basis for the following description of the liquid-blacking feedin mechanism, which is the subject matter 0% this application.

Upon each side of the carriage is supported a stationary liquid-blocking tank, as 23 and 24, and as these tanks and their connections are identical, a description of medium of alower transverse shaft 34,.

7 forms a crank gear on the sha rod 29 (see Fig. 5) is actuated through the ear 30 which 31, and this gear is rotated through the gear 32 on shaft 33. The shaft33 is rotated through the medium of the intermediate (supported in the carriage) by means of sprocket wheel 35, chain 36 and sprocket 37, at the right in Fig. 4. In Fig. 1 it will be seen that the shaft 34 is driven from shaft 10 by means of the bevel gears 38 and 39.

The clutch member 40 on shaft 33 (Fig. 10) is moved into operative position with the complementary member 41 of the-wheel 32, by movement of the lever arm 43, pivoted at 44 to the post 45 of the frame 4. At its lower end, the lever is urged outwardly by a flat spring 46, and when under action of the spring the clutch is held disconnected by the lever. It is intended that the clutch shall be intermittently connected, and. I have arranged the mechanism so that the clutch is connected during one reciprocation of the carriage out of every six movements of the carriage. It is assumed that six reciprocatiolis of the carriage 4 will be suflicient to enable the brushes to shine the shoe, and durin one of the reciprocating movements, it is esigned that'the liquid-blacking shall be fed to the shoe, and after this one movement, that the .suppl of blacking shall be cut-off. To attain t is purpose a ratchet wheel 47 is journaled in post 45 on the stud shaft 48, and it will be noted that the ratchet wheel has six teeth. The wheel is arranged to rotate in proximity to the lower end of the lever arm 43, and is provided with a cam lug 49 in the path of movement of which the lever arm is located. A pawl 50 (Fig. 5) is pivoted on a post 51 and the sprin 52 forces it toward the stop pin 53 fixed 1n the post. This post is located at the end of the movement of the carriage 4, and the pawl is in position'to engage one ofthe teeth of the ratchet wheel 47. Thus with each reciprocation of the carriage, the pawl engages the ratchet wheel and turns it one tooth. When the lug 49 engages the lower end of the lever 43, the clutch. members 40 and 41 are connected and the-air compressor or pump is actuated from "the gears 32, 30, shaft 31 and piston rod or plunger 29. Upon the next reciprocationpf, the carriage the ratchet wheel is turned contact with the pawl, the lug is moved so that the lower end of the lever is freed, and the spring moves the lever arm so that the clutch is disconnected. In this manner the air compressor is stopped.

Air is forced from the compressor cylinder 28 throu h pipe 53, and this pipe is connected to t e air supply pi e 54 by means voir 58 is interposed in the an supply pipe,

and fromthis reservoir the feed pipes 59 and 60 extend toward the ends of the nozzles 25 and 26 of the tank. Air is introduced into the blacking tank, from pipe 59 through the regulator or dome 60 which is located on to of and opens into the blacking tank. T is regulator has a rotary top 61 whose perforation 62 is adapted to register with the perforation 63 in the closed top 64 of the dome. By moving the rotary top so that the perforations will register to a greater degree the pressure within the tank may be reduced by outlet to atmosphere, and in this way the feed of blacking is regulated.

The blacking is forced from the tank under pressure through the pipe'65 which has an inlet 66 inside the tank, for blaekin and connects with the nozzle 27 from whic it is sprayed by air pressure through air feed pipe 59 or 60 as the case may be. In. this manner, during one reciprocation of the carriage, the liquid blacking is sprayed upon the shoe from each side.

The machinery is operated from the motor 12 and the motor is set in motion from the presence. of a coin dropped into the chute.

be understood that each shoe is shined by the six reciprocatory movements of the brushes, during one ofwhich reciprocations, and only one, the liquid blacking is fed to the shoe as described. By proper manipulation of the coin, the second. shoe is caused to be shined as before described.

For a more comprehensive understanding of the devices other than the blacking- ;feeding mechanism, reference should be had ,to the parent application.

What I claim is .ciprocating carriage carrying[ a blacking tank having nozzles and a pump to force the blacking through the nozzles, with means operative on certain reciprocat-ions of the carriage to operate the pump.

2. The combination of a footrest, a reciprocating carriage carrying a blacking tank having nozzles and a pump; actuating means for the pump including a clutch and lever, a ratchet having means to engage the lever, and a pawl pivoted on a stationary member to engage the ratchet, for the purpose described.

3. In a shoe shining machine, the combination with a reciprocating carriage and a liquid blacking tank formed with a plural- I ity of nozzles and an air compressor, of a toothed cam wheel on the carriage, a pawl pivoted on a fixed member of the machine to enagage the wheel at certain reciprocations of the carriage, and a lever actuated by the cam wheel for operating the compressor.

In testimony whereof I aifix my signature in presence of two witnesses.
